摘要: |
荒漠具有高度干旱、植被稀少和强辐射等特征,是极端放线菌资源的宝库。近年来,多种荒漠来源的放线菌新分类单元和新结构活性天然产物被报道,引起了人们的极大兴趣。了解荒漠放线菌的群落结构特征,选择有效的分离方法是挖掘荒漠放线菌物种资源的关键。本文综述了全球主要荒漠区放线菌的资源分布与多样性,归纳分析了荒漠放线菌的主要分离方法及存在问题,并对未来的研究工作进行了展望。 |

Abstract: |
Desert is characteristic of high aridity, sparse vegetation and intense radiation and thus is a treasury of extreme Actinobacteria. In recent years, multiple novel Actinobacteria taxa and related bioactive natural products have been retrieved from desert habitats, which has drawn much attention from microbiologists. Understanding actinobacterial community structure and selecting effective isolation methods are the key to mining actinobacterial resources in desert ecosystems. This review summarizes actinobacterial diversity and distribution in major desert regions worldwide, main isolation methods and current problems for isolating actinobacterial resources, and prospects for future research work. |
